I am trying to just pass a simple value across and seem to be encountering a problem.  
Any suggestions on this? I have confirmed the value being set is a Unsigned32

[  
{  
"oid": "1.3.6.1.4.1.29956.3.1.2.1.1.6.1",  
"type": "Unsigned32",  
"value": "9"  
}  
]

I am getting an error as "NoSuchName"

I have not used that node, but I wonder whether it should be  
`"value": 9`  
as "9" is a string not an Unsigned 32.  
Otherwise, in a terminal run

```bash
node-red-stop
node-red-start

```

and post us the log up to the error message.

I changed to the following and now get a different error. Notwritable  
[

Sorry could you put in the right direction to what you mean by terminal? Sorry I am very new to this.

where are you trying to set this?  
What is your flow? Are you using node-red-node-snmp?

In addition to @ukmoose's questions, what computer and operating system are you running on? A terminal window is a window where you type commands (a throwback to when a computer would have a keyboard/display known as a terminals to control the computer).

I am using Windows 7, I tried using putty as terminal. Not sure if it needs to be SSH, and trying 127.0.0.1 port 1880 would not work with putty.

I start up with node.js then just type in node-red in Windows cmd prompt.

If you look back I asked that you run node-red-stop then node-red-start and post the log from that point so we can see the startup messages too. It is preferable to copy/paste the text rather than an image if possible.

OK, perhaps those don't work on Windows. I don't know.

Have you tried doing a get on that object? If that works ok then perhaps you do not have write access to the object.

I have been able to _GET_ values with no problem and when I walk the MIB file it shows read-write for that value. That is something to consider though, I will try a couple other values to see if I am able to write to any other values. I will try some different data types as well.

I notice that in the flow you posted you have an inject and a slider feeding the snmp node. What are you using for the testing?

The inject is configured to send a timestamp, not a value, or is the value defined in the node? I don't have the node installed so I can't see what you have configured.

I was under the impression the value in the code was what number the node was pushing. If that is not the case then there lies my problem. In the case of the slider, it would have to be the msg.payload from that node. For the ease of getting it to work was trying just the inject. Here is the example given in the node information. I am trying to use OID of course the OID address, the type as datatype defined in MIB file, and value is what I want set to that specific OID. Is that how you are reading this, or am I in error?

```auto
    {
        "oid": "1.3.6.1.2.1.1.5.0",
        "type": "OctetString",
        "value": "host1"
    },
    { "oid": ... }
]
```
